SILO.

To all whom it may concern:

Be it known that 1, MAX H. J AHN, a citizen of the United States,residing at Mayfield, in the county of Fulton and State of New York,have invented certain new and useful Improvements in Silos, of which thefollowing is a specification.

The object of this invention is to provide means whereby a farmer maybuild a silo of any desired height without the use of an extensive setof tools. A further object of the invention is to provide a silo whichmay resist the action of frost upon the feed placed therein, and a stillfurther object of the invention is to provide means whereby the capacityof the silo may be increased as the need therefor arises.

The invention is illustrated in the accompanying drawings, in which-Figure 1 is an elevation of a s1lo embodying my improvements;

Fig. 2 is an enlarged vertical section on the line 22 of Fig. 1;

Fig. 3 is an enlarged horizontal section on the line 33 of Fig. 1;

Fig. 1 is a perspectlve view of two of the sections of which the silo iscomposed;

Fig. 5 i a vertical sectional View illustrating the manner of anchoringthe S110 so that it will resist the action of high Winds.

In carrying out my invention, I employ sections which are superposed toform the wall of the silo and these sections each consists of inner andouter rails or plates 1 and 2 which will preferably be boards or stripsof lumber. The said plates or strips are secured to opposite sides ofstuds 3 which are disposed near the ends of the strips and are soarranged that their upper ends will project above the upper edges of thestrips, while their lower ends .will be above the lower edges of thestrips. The ends of the strips 1 and 2 are beveled, as shown at 4, andsaid ends are staggered with reference to the studs, that is to say, asshown most clearly in Fig. 3, the strips or boards are arranged so thatone end of the outer strip will be nearer the stud than thecorresponding end of the inner strip while the opposite end of the outerstrip will be more remote from'the adjacent stud than the correspondingend of the inner strip. This arrangement permits the meeting ends of thesections in the same tier or course of the silo to overlap so that theinner strip of one section will bear against the inner surface ofSpecification of Letters Patent.

' the outer strip of the meeting sectionand will, in turn, have itsinner surface bearing against the adjacent end of the inner strip of themeeting section so that the sections will be mutually braced andinterlocked at their meeting ends. The beveling of the ends of thestrips, moreover, permits the strips to fit togetherin angular relationso that a silo of polygonal horizontal outline may be formed. It will beapparent, upon reference to Fig. 3, that the meeting ends of the outerplates will form seams or joints.

These seams or joints I cover by metallic strips 5 which are nailed orotherwise -secured to the outer surfaces of the sections and extend overthe meeting ends so that the joints will be thoroughly covered and theaccess of frost or moisture to the interior of the silo will beprevented.

It will, of course, be understood that the sections are superposed so asto build the silo up to any desired height and the sections are broughtautomatically into vertical alinement by causing the lower'ends of thestuds in an upper section to rest upon the upper ends of the studsin'the immediately subjacent section. The sections will thus be made toregister without requiring an extraordinary amount of care upon the partof the builder and shifting of an upper section inwardly or outwardlywill be prevented by the engagement of the studs between the strips orboards of the upper section, collapse of the silo v being therebyavoided. I

In one wall of the silo, I employ at intervals short sections 6 whichhave their inner endsclosed by posts 7 whereby a door frame is produced.The faces of the door frame converge inwardly, as shown clearly in Fig.3 and withinthe door opening I fit a door 8 which is composed of innerand outer walls whereby an air space 9 is provided in the door. Toretain the doors in position, I employ a locking bar across the outerface of each door and this locking bar consists of sections 10 which arehinged together at their centers, as indicated at 11, so that the barsmay be folded upwardly but will be prevented from folding downwardly andthe intermediate portion of each bar is off- 7 as shown at 13, to theadjacent door frame and the opposite end engages a loop or keeper 14 sothat the bars will'be held in contact with the outer surfaces of thedoors and will thereby retain the doors in position.

In order to insure stability in the structure, I place the lowersect-ionsupon a foundation 15 of concrete or similar material in whichis anchored the lower end of a' stay 16 which extends upwardlythroughthe silo between the inner and outer walls thereof and has its upperextremity threaded,

as shown at 17, and inserted through a cap plate 18 fitting on andbridging the upper edges of the inner and outer walls. A nut 19 ismounted on the threaded extremity of the stay and is turned home againstthe cap plate so as to clamp the superposed sections in their superposedrelation as will be readily understood. The stay 16 may consist of ametallic rod or bar or a series of rods or links having their endsconnected in any convenient manner, the number of the rods or linksdepending upon the height of the silo. A roof of any desiredconstruction may tions may be furnished in various sizes so that a siloof any desired diameter may be formed therefrom and, as the sections aremerely placed one upon another and the forms of their ends prevent'thembeing placed end to end except in the prescribed manner, the silo may berapidly build by unskilled labor. The stays by which the silo isanchored in place pass up through 'thewaflls so that they do not detractfrom the appearance of 'thesilo nor interfere with the placing of foddertherein and the construction of the-independent sections is such the tthe completed silo will have inner and outer walls with a dead airspacebetween them and, therefore, the contents of the silo will be protectedagainst the actlon of frost or excessive changes 1n temperature. I Thecost of the several sections is obviously very slight and a silo ofconsiderable capacity maybe built without incurring a burden someexpense. Moreover, a comparatively smallsilo may be. originally builtand the height of the same extended from season to season so that thecost of a silo of great capacity may be very easily met.

Having thus described my invention, what is claimed as new is:

-A hollow-wall silo composed of superposed and abutting panels, eachpanel conslstmg of vertical studs and inner and outer horizontal stripssecured to the opposite sides of the studs, the studs being spaced fromthe ends of the strips and the upper and lower-ends of the studs beingrespecti ely above the upper and lower edges of the-strips whereby thestuds of each panel will enter a superposed panel with the studs of allsuperposed panels in, vertical alinement and the studsof eachsuperposedpanel resting on the studs of asubjacent panel, and the ends of thestrips projecting beyond the studs in staggered relation with theopposite ends of the strips beveled in opposite directions whereby theinner stri p of a panel Wlll bear at one end against the lnner side ofthe inner strip of one abutting 'panel at a point spaced from the end-ofthe latter and at itsop'posite end will extend across another abuttingpanel and bear against the inner side of the outer strip thereof betweenthe end of the same and the adjacent stud, and the-outer strip of eachsection will bear at oneend against the inner face of the outer strip ofan abutting section and at its opposite end; will have its beveled edgeflush with the outer face of the outer strip of another abuttingsection, covering'strips secured upon the outer faces of abutting panelsat the vertical joints be- ,tween' the same, and means for anchoring thesuper-posed panels.

In testimony whereof I afiix my signature.
